The unofficial spokesman for the Heart Attack Grill restaurant in Las Vegas - which prides itself on 'taste worth dying for' - has died of a heart attack at the age of 52.

John Alleman visited the infamous restaurant, which holds the Guinness world record for the 'most calorific burger', on a daily basis and would often stand outside encouraging other people to enter.

He suffered a heart attack last week and was rushed to Sunrise Hospital, where he remained until doctors removed his life support on Monday.

'He'd say, "I just love your place, Jon." He's the only person I know who was
probably at the restaurant more than I.'
